Abstract
An electronic, programmable device for controlling the motion of compressor valve elements, wherein the device receives an incoming signal from a velocity sensor located on a compressor valve; filters, amplifies, and processes the incoming signal by a control algorithm; and responds to the incoming signal by creating an output signal that produces an actuator force that is applied directly to a moving valve element and associated methodology.
Claims3
An electronic, programmable device for controlling the motion of compressor valve elements in a reciprocating compressor, wherein the device:
- receives an incoming signal from a velocity sensor located on a compressor valve and an additional incoming signal from at least one other sensor selected from the group consisting of:
- a key phasor, a motor or engine drive shaft encoder, and a sensor synchronized with an operating reciprocating compressor;
- filters, amplifies, and processes the incoming signal and additional incoming signal by a control algorithm;
- and
- responds to the incoming signal and additional signal by creating an output signal that produces an actuator force that is applied directly to a moving valve element.
An electromagnetically actuated valve that is controlled by an electronic, programmable device, wherein the device:
- receives an incoming signal from a velocity sensor located on the electromagnetically actuated valve and an additional incoming signal from at least one other sensor selected from the group consisting of:
- a key phasor, a motor or engine drive shaft encoder, and a sensor synchronized with an operating reciprocating compressor;
- filters, amplifies, and processes the incoming signals by a control algorithm;
- and
- responds to the incoming signals by creating an output signal that produces an actuator force that is applied directly to a moving valve element of the electromagnetically actuated valve.
A valve comprising a valve housing having at least one input port and at least one output port;
- a plate within the housing the moves up and down within the housing to control passage of fluid through the valve;
- at least one shaft attached to one side of the plate at least one magnet attached to the shaft;
- at least one coil surrounding the shaft that is operable to sense motion of the plate and to control the motion of the plate, the valve further comprising:
- an electronic, programmable device for receiving a signal from at least one coil, for interpreting the signal as motion of the plate, and for delivering a signal to at least one coil to control motion of the plate wherein the programmable device filters, amplifies, and processes the signal by a control algorithm wherein said programmable device:
- receives an incoming signal from a velocity sensor located on the electromagnetically actuated valve;
- filters, amplifies, and processes the incoming signal by a control algorithm;
- and
- responds to the incoming signal by creating an output signal that produces an actuator force that is applied directly to a moving valve element of the electromagnetically actuated valve.
